FRANK HEMBES, OF CHICAGO, ILLINOIS.

FLY-ESCAPE FOR SCREENS.

Application filed December 16, 1916.

To all whom it may concern:

Be it known that I, FRANK HEMBES, a citizen of the United States, and a resldent of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in F ly- Escapes for Screens; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the numerals of reference marked thereon, which form a part of this specification.

This invention relates to an improved form of door or window screen wherein the upper rail of the frame has a metallic casing disposed below the inner face thereof to afford a dark chamber adaptable as a fly trap and having a front portion provided with openings permitting flies or other insects to escape from the inside of the screen through the casing and out through a suitable opening provided between the upper ed e of the screening and the openings in the casing, the construction of the screen and easing effectively preventing the entrance of flies or other insects through said openings into a room equipped with window screens of this type.

It is an object of this invention to construet a means attachable to a window screen to permit the escape of flies and other insects from a room, and effectively preventing the entrance of the sameinto the room.

It is also an object of this invention to construct a window screen adapted to permit the exit of flies from a room and preventthe entrance thereof.

It is finally an object of this invention to provide an adjustable device for use on fly screens of various sizes, simple and inexpensive of construction adapted to be readily attached in place to serve as a fly trap and also adapted to permit the escape of flies from a room without permitting the entrance of the same into the room.

The invention (in a preferred form) is illustrated in the drawings and hereinafter more fully described.

In the drawings Figure 1 is a perspective vertical sectional view through a window screen equipped with a device embodying the principles of my invention.

' Fig. li a slightly enlarged vertical section taken on line H of Fig. 3, showing parts of the screen frame.

Fig. 5 is a sectional view taken on line 55 of Fig. 2.

As shown in the drawings:

The invention comprises an adjustable casing or tubing consisting of two telescoping sections, denoted as a whole by the reference numerals 1 and 2, as clearly shown in Fig. 2, and adapted by adjustment to fit into window screen frames of different sizes.

As shown in the drawings, a screen frame, comprising a bottom rail 8, a top rail 4, and stiles 5, connecting said rails 3 and 4, has attached thereto by any suitable means a wire screening 6, the upper edge of which on tends to within a short distance of the upper rail a, providing an opening as shown in Fig. 1, for a purpose hereinafter described.

The casing section 1, is made of metal or other suitable material bent or formed to afford a right angled channel portion comprising a back or base 7, an upper side 8, and a lower side 9. Bent upwardly at right angles to the upper side 8, and then downwardly upon itself is an integral flange or front piece 10, having an integral wing or flap 11, at the outer end thereof. Cut or stamped from the lower portion of the front piece 10, are a plurality of equidistantly spaced tongues 12, bent inwardly at right angles to lie flat against the upper channel side 8, and then bent downwardly parallel to the channel back 7, and to the w're screening 6, and disposed behind the opening aflorded between the upper edge of said wire screening and the lower edge of the top rail 4. The tongues 12, thus stamped and bent rearwardly afford a plurality of rectangular openings 13, separated from one another by parallel strips or slats 14, and each having struck outwardly therefrom downwardly directd clips or fasteners 15, adapted to engage over the upper edge of the wire screening 6, and lie fl at against the front surface thereof to rigidly hold the same in position. The forward or front edge of the lower channel side 9, is cut or stamped to afford a plurality of openings 16, registering with the openings 13, and separated by nubs or fingers 17, which contact the lower ends of the strips 1 1, and may be soldered or secured thereto by other suitable 7 smaller to'permit thestunetobe telescoped into the section 1, to fit into the screen frame, after which-:the sect-ions are rigidly fastened in position. v

The operation is as follows:

The window screen, on which it is desired tomount the telescoping sections 1 and 2, is first arranged to have the wire screening 6, cut or lowered sothat its upper edge extends to within a :short distance of the lower front edge of the upper rail 4. The section 2, is 'then telescopedintothe section 1, until the length of the casing is such that it will fit between the stiles 5,-with'the upper channel sides 8, contacting the lower surface of the npperrail 4,-and with the rear surfaces of the front piecesilO, and the vflaps 11, en gaged against the front surfaces of the upper'rail 4, and the'stiles 5, asclearlyshown in Fig. 1; The clips 15, are then engaged over the upper edge of the screening 6, and bent downwardly against the front surface thereof, and the-casing and screening is then securely: fastenedv in position by means of the screws-19, which engage through the apertures 18, provided for the purpose.

With the casing and the wire screening in position as described and as shown in Fig. 1, an escape is provided'for fiies. whichmay travel upwardly through-the openings 16, into-the front portion of the channel chambers-78-9, of the sections 1 :and 2. i The rear portions ofthe channel chambers, however,- being-darkcned by the tongues 12, and the strips ld, serve-as a trap for flies which find their way thereiinwhile other flies in the forward portion of the channel chambers seeking the lightand on account of their habit :of moving upwardly continue on their way passing through the rectangular openings 13, to the outside of the window screenthrough' .the opening afforded be tweenthe upper edge of thewire screening 6, and-the upper edge of the framing form ing the openings 13.

While the device in combination with the window screen as described, serves as a trap and 1also-affordsan escape for flies? from a room in which -tlie window screen is used,

Copies of'this patent may be obtained for:

it also acts effectively to prevent the en trance of flies into the room, due to the fact that the chambers afforded by'the sections -1 and-2,-are darkened by the tongues 12 and the strips 14:, and since flies do not travel downwardly into dark spaces, they will not try to enter the room over the upper edge of the screening 6, through theopenings 13 and-16.

It wlll, of course, be understood that the casing may be made of but a single sect on to. fit within a window s'creenof acertain size, or that the device may be made of a center section: constructed similar to that described, buthaving telescoping end pieces to permit :adjustability for i tting the device to window 'screens'of different sizes.

. I am aware that various other details of construction may be varied through'a wide v range without-"departing from the princiand afford aseries of openings therein,

strips separating said' openings, and means struck outwardly from said strips adapted to engage over the upper edge of'said wire screening, said-openings affording a means for the escape of flies from behindthewire screening, and said darkened chambers serv ing as a trap for fiies and alsowtending to effectively prevent the entrance of flies through said openings.
